You need to debug your flash writing. This is board and processor
specific, and I have basically no knowledge of either so I can only give
Try writing to flash using command line commands, erasing flash, etc.
Once that works, figure out where in flash your env is being saved...
see if anything is being saved there when you do the "saveenv", why it
isn't being saved or why it is being corrupted.
